London has become Europe's TB capital because primary care trusts are failing to adopt measures drawn up four years ago, MPs and health campaigners say.

Just 55% of PCTs in England routinely screen new immigrants, according to a poll by the All-Party Parliamentary Group on Global Tuberculosis.

One PCT with a very high TB rate had even scrapped its screening programme.

It has always struck me as strange that movements of livestock are much more intensely regulated than movements of people—even though movements of people have much bigger potential health effects.
